DEFINITIONS In this Agreement (and where the context so permits) the single of the terms defined below shall include the plural and vice versa. The following terms shall have the meanings identified below. “Affiliate” means an entity, which is (i) directly or indirectly controlling such party, (ii) under the same direct or indirect ownership or control as such party, or (iii) directly or indirectly owned or controlled by such party. For these purposes, an entity shall be treated as being controlled by another if that other entity has fifty percent (50%) or more of the votes in such entity, is able to direct its affairs and/or to control the composition of its board of directors or equivalent body. “Chief Maintainer” means the individual initially appointed to lead, direct, and manage the Qt Project by The Qt Company and, in subsequent periods, the individual elected by a simple majority the Qt Project maintainers to lead, direct and manage the Qt Project. “Contributions” means the code, documentation or other original works of authorship, including without limitation any modifications or additions to an existing work, that are submitted via any form of electronic, verbal, or written communication to the Qt Project for inclusion in, or documentation of, Qt Software. “GNU License Terms” means all software licenses copyrighted by the Free Software Foundation, currently in use or hereafter published, including, but not limited to, the GNU General Public License versions 1 through 3, the GNU Library General Public License versions 1 through 2 or the GNU Lesser General Public License versions 2.1 through 3.0. “Licensor Contributions” means Contributions submitted by Licensor, or if applicable Licensor’s employee(s). “Open Source Software” shall mean any software component, application or collection of files in human- or machine-readable form that is publicly available in source code form and licensed under an open source license listed at http://www.opensource.org/licenses or similar license. “Qt Project” means the open source software project initially created by Nokia Corporation, aimed at developing Qt Software. “Qt Software” means any Qt software and any Contributions, related “online” or electronic documentation, associated media and printed materials, including but not limited to the source code, object code, example programs, tools, add-ons, plug-ins, companion products and documentation. “Third Party Contributions” means Contributions that are copyrighted or owned by a party other than the party submitting the Contribution. “Update” means a release or version of the Qt Software containing enhancements, new features, bug fixes, or error corrections. 2. PURPOSE OF THE AGREEMENT 2.1 Purpose In order to participate in the development of Qt Software, The Qt Company requires Licensor to accept the terms and conditions contained in this Agreement. This Agreement is primarily required because The Qt Company has existing obligations regarding the Qt Software and wants to enable the broadest, most vibrant Qt ecosystem. This agreement facilitates The Qt Company’s compliance with the spirit of its commitments to the Open Source Community, under the agreement with the KDE Free Qt Foundation, and enables participation of commercial Qt users in the Qt Project. 2.2 General Licensor wishes to participate in the development of Qt Software. Licensor accepts and agrees to the following terms and conditions for Licensor’s present and future Licensor Contribution(s) submitted to The Qt Company and/or the Qt Project. If Licensor does not agree to the terms and conditions contained in this Agreement, Contribution(s) cannot be accepted and Licensor cannot contribute code or participate in the development of Qt Software. 2.3 Third Party Contributions Third Party Contributions are not accepted under the terms of this Agreement. Third Party Contributions may only be accepted for use in Qt Software or by the Qt Project if the following criteria are met: (a) The Third Party Contribution is licensed under license terms that are compatible with the GNU Lesser General Public License version 2.1 (“LGPL v. 2.1”) as included on the Free Software Foundation’s website (www.gnu.org); and (b) If the Third Party Contributions are licensed under either: (i) GNU License Terms; or (ii) license terms requiring as a condition of use, modification and/or distribution of the software subject to the license, that the software or other software combined and/or distributed with it be disclosed or distributed in source code form; licensed for the purpose of making derivative works; or redistributable at no charge, both the Chief Maintainer and The Qt Company must give their unanimous, prior, written consent before such Third Party Contribution may be included in the Qt Project. The modules for which consent has been obtained will be posted on the Qt Project web site. (c) Notwithstanding (a) and (b) above, a Third Party Contribution which is an Update to third party code already included in Qt Software may be used to replace such third party code previously included in Qt Software provided that the Update is licensed under the same license terms as the code it is replacing. The Chief Maintainer shall remove, from the public Qt code repositories or project website, any Third Party Contribution which does not meet the criteria specified above. 3.
